Start by putting in the IC sockets.
Then pick a section next to a socket and put in a few components that connect to each other and/or to the socket. (See below for details on how each component goes in.)
Then turn the board over and twist, solder, snip (see below).
Pick another area next to the area you just did and put the components in, twist, solder, etc..
Repeat this process till you fill the whole board
When you get to a wire (an X or a dot that has a label on it, like “vol 2”), just skip it for now. Later, a wire will go here.
